I had 3 cups of coffee yesterday. The last time I did this I posted here because I went lucid. Well, I went lucid again. Just like last time, I woke up in the middle of the night and couldn't sleep for hours. I cycled (SSILD term), and later became lucid.

There may be something to caffeine, but I'll only take it as it comes naturally. I don't want to try to become lucid by purposefully using caffeine.
